Secret Sessions of the House and Senate: Authority, Confidentiality, and Frequency

Summary
Secret, or closed, sessions of the House and Senate exclude the press and the public. They may be
held for matters deemed to require confidentiality and secrecy—such as national security,
sensitive communications received from the President, and Senate deliberations during
impeachment trials. Although Members usually seek advance agreement for going into secret
session, any Member of Congress may request a secret session without notice. When the House
or Senate goes into secret session, its chamber and galleries are cleared of everyone except
Members and officers and employees specified in the rules or designated by the presiding officer
as essential to the session. After the chamber is cleared, its doors are closed.
Authority for the House and Senate to hold secret sessions appears in Article I, Section 5, of the
Constitution: “Each House may determine the Rules of its Proceedings…. Each House shall keep
a Journal of its Proceedings, and from time to time publish the same, excepting such Parts as may
in their judgment require Secrecy....” Both chambers have implemented these constitutional
provisions through rules and precedents.
In the House, Rule XVII, clause 9, governs secret sessions, including the types of business to be
considered behind closed doors. In addition, House Rule X, clause 11 authorizes the House
Permanent Select Committee on Intelligence to bring before the House material to help it
determine whether classified material held by the committee should be made public.
In the Senate, under Senate Rule XXI, the presiding officer exercises no discretion about going
into secret session. Any Senator may make a motion that the Senate go into closed session, and, if
seconded, the Senate will immediately proceed into a secret session. Once in a secret session, the
Senate operates under applicable portions of Senate Rules XXIX and XXXI.
The Senate met in secret until 1794, its first rules reflecting a belief that the body’s various
special roles, including providing advice and consent to the executive branch, compelled it to
conduct its business behind closed doors. Since 1929, when the Senate began debating
nominations and treaties (referred to as executive business) in open session, the Senate has held
56 secret sessions, generally for reasons of national security or for consideration of impeachment
proceedings.
The House met frequently in secret session through the end of the War of 1812, mainly to receive
confidential communications from the President, but occasionally for routine legislative business.
Subsequent secret meetings were held in 1825 and in 1830. Since1830, the House has met behind
closed doors only four times: in 1979, 1980, 1983, and 2008.
A chamber’s rules apply during a secret session. The proceedings of a secret session are not
published unless the relevant chamber votes, during the meeting or at a later time, to release
them. Then, those portions released are printed in the Congressional Record.
This report will be updated as events warrant.

Secret Sessions of the House and Senate: Authority, Confidentiality, and Frequency

ecret, or closed, sessions of the House and Senate exclude the press and the public. They
may be held for matters deemed to require confidentiality and secrecy—such as national
S security, sensitive communications received from the President, and Senate deliberations
during impeachment trials.1 Although Members usually seek advance agreement for going into
secret session, any Member of Congress may request a secret session without notice.2 When the
House or Senate goes into secret session, its chamber and galleries are cleared of everyone except
Members and officers and employees specified in the rules or designated by the presiding officer
as essential to the session. When the chamber is cleared, its doors are closed.
Authority: Constitution, Chamber Rules, and
Precedents

Authority for the House and Senate to hold secret sessions appears in Article I, section 5, of the
Constitution: “Each House may determine the Rules of its Proceedings.... Each House shall keep
a Journal of its Proceedings, and from time to time publish the same, excepting such Parts as may
in their Judgment require Secrecy....” Both chambers have implemented these constitutional
provisions through rules and precedents.3
In the House, Rule XVII, clause 9, governs secret sessions. A secret session may be held when the
House has received confidential communications from the President or when a Member informs
the House that the Member has communications that should be kept secret. A secret session may
occur pursuant to a special rule or by a motion to resolve into a secret session made in the House.
Such a motion is in order in the House; is not in order in the Committee of the Whole. A Member
who offers such a motion announces the possession of confidential information and moves that
the House go into a secret session. The motion is not debatable, and no point of order is available
to require the communication at issue to be disclosed before the vote. If the motion is agreed to
by a simple majority (a quorum being present), the chamber and galleries are cleared. When the
only persons present are Members, officials allowed under Rule XVII, clause 9, and staff
designated by the Speaker as essential to the proceedings, the chamber doors are closed, and the
House begins the secret session. The Member making the motion is then recognized under the
hour rule for debate.4
In addition, under Rule X, clause 11, paragraphs (g)(2)(D) through (g)(2)(G), the House Select
Committee on Intelligence may move that the House hold a secret session to determine whether
classified information held by the committee should be made public. This procedure is invoked
only if the committee desires such a disclosure and the President personally objects to it.

1 Congressional committee meetings that are closed to the public are sometimes called executive sessions.
2 On November 1, 2005, Senate Democrats compelled a secret session of the Senate with no notice. See Charles
Babington and Dafna Linzer, “Senate Democrats Force Closed Meeting,” Washington Post, November 2, 2005, pp. A1,
A4.

Secret Sessions of the House and Senate: Authority, Confidentiality, and Frequency

In the Senate, any Senator may make a motion that the Senate go into closed session, and, if
seconded by another Senator, the Senate will immediately proceed into a secret session.5 Under
Senate Rule XXI, the presiding officer exercises no discretion about going into secret session if
the motion is made and seconded. The motion is not debatable. A Senator may interrupt another
Senator to make the motion and may cause the other Senator to lose the floor.6
Once in a secret session, the Senate operates under applicable portions of Senate Rules XXIX and
XXXI. Rule XXIX specifies which of the Senate’s officers and staff may stay during the closed
session and authorizes the presiding officer to include other staff at his discretion. Rule XXXI
requires Senate business to be transacted in open session, but states that the Senate by majority
vote may determine that a specific treaty, nomination, or other matter may be considered in secret
session. A motion to return to open session is in order at any time, is not debatable, and requires a
simple majority vote, a quorum being present.
When the Senate is conducting an impeachment trial, it may hold deliberations behind closed
doors. During this time, Senate standing rules are supplemented by additional rules, called “Rules
of Procedure and Practice in the Senate when Sitting on Impeachment Trials.”7
Confidentiality and Publication Requirements
Members and staff of both houses are prohibited from divulging information from secret sessions.
In the Senate, staff are sworn to secrecy, whereas in the House, staff must sign an oath not to
reveal what happens in the secret session, unless the House decides to make its actions public.
Violations of secrecy are punishable by the disciplinary rules of a chamber. A Member may be
subject to a variety of punishments, including loss of seniority, fine, reprimand, censure, or
expulsion. An officer or employee may be fired or subject to other internal disciplinary actions.8
The proceedings of a secret session are not published unless the relevant chamber votes, during
the meeting or at a later time, to release them. Then, those portions released are printed in the
Congressional Record.
Under Rule XVII, if the House decides not to release the transcript of a secret session, the
Speaker refers the proceedings to the appropriate committee(s) for evaluation. The committees
are required to report to the House on their ultimate disposition of the transcript. If a committee
decides not to release the transcript, it becomes part of the committee’s noncurrent records
(pursuant to House Rule VII, clause 3) and is transferred to the Clerk of the House for transmittal
to the Archivist of the United States at the National Archives and Records Administration.
Transcripts may be made available to the public after 30 years unless the Clerk of the House

5 Until 1929, the Senate routinely considered treaties and nominations (executive business) in closed executive session,
but since then only rarely has the Senate used that method.

determines that such availability “would be detrimental to the public interest or inconsistent with
the rights and privileges of the House” (Rule VII, clauses 3 and 4). If the Senate does not approve
release of a secret session transcript, it is stored in the Office of Senate Security and ultimately
sent to the National Archives and Records Administration. The proceedings remain sealed until
the Senate votes to remove the injunction of secrecy.9
Frequency of Secret Sessions
The Senate met in secret until 1794,10 its first rules reflecting a belief that the body’s various
roles, including providing advice and consent to the executive branch, compelled it to act behind
closed doors. Although legislative session were generally open after 1795, the Senate’s executive
sessions (to consider nominations and treaties) were usually closed until 1929.11
Since 1929, the Senate has held 56 secret sessions, generally for reasons of national security or
for consideration of impeachment questions. On December 20, 2010, for example, the Senate
met in closed session to discuss the New Start Treaty with Russia (Treaty Doc. 111-5). On
December 7, 2010, the Senate met in closed session to debate the impeachment of federal judge
G. Thomas Porteous, Jr., of Louisiana. Six secret sessions were held during the impeachment trial
of President William J. Clinton in 1999.12 In 1997, the Senate met in secret to consider the
Chemical Weapons Convention Treaty and, in 1992, to debate the “most favored nation” status of
China. Table 1 identifies the 56 secret sessions of the Senate since 1929.
The House met frequently in secret session through the end of the War of 1812, mainly to receive
confidential communications from the President, but occasionally for routine legislative business.
Subsequent secret meetings were held in 1825 and in 1830. Since 1830, the House has met behind
closed doors only four times: in 1979, 1980, 1983, and 2008.13 Table 2 identifies secret House
sessions since 1825.

9 S.Res. 243 of the 100th Congress established the Office of Senate Security within the Office of the Secretary of the
Senate. In part, the office is responsible for establishing Senate policy on the handling of classified matters. See Senate
Manual
, standing orders, pp. 189-192.
10 According to the Senate Historian’s Office, “The framers of the Constitution assumed that the Senate would follow
their own practice, as well as that of the Continental Congress, of meeting in secret.” See http://www.senate.gov/
artandhistory/history/minute/The_Senate_Opens_Its_Doors.htm.
11 In its discussion of executive sessions, the Senate Historian’s Office says that after six years of Senate operation,
“pressure from the state legislatures then electing senators caused a change in policy. In a compromise, the Senate
agreed to open its legislative proceedings, but to conduct all executive business related to nominations and treaties in
private.” See http://www.senate.gov/artandhistory/history/minute/Executive_Sessions.htm.
12 On January 8, 1999, the Senate Democratic and Republican Conferences held a rare joint closed meeting in the old
Senate chamber to discuss the procedure for the pending impeachment trial of the President, but this was not a formal
secret session of the Senate.
13 On July 27, 1998, the House had a secret briefing from law enforcement officials the chamber to receive information
related to the shooting of two Capitol police officers on July 24, 1998. On March 18, 1999, the House had a closed
meeting to discuss “highly classified material relating to the emerging ballistic missile threat to the U.S.” This meeting
was not considered a “secret session,” because it was conducted by a former Defense Secretary who was the chair of
the Commission to Assess the Ballistic Missile Threat to the United States. After the meeting, the House convened to
consider legislation to deploy a national missile defense. The session was for Members only and was conducted at the
“top secret classification level.” Source: “Dear Colleague” letter from the Speaker of the House, dated March 15, 1999.
